CABLE-CLAMP.

To all whom it may concern:

Be it known that I, HARRY C. SoHArFnR- NOGKER, a citizen of the UnitedStates, residing at Leetonia, in the county of Columbiana and State ofOhio, have invented a certain new and useful Improvement in Cable-Clamps, of, which the following is a full, clear, and exact description,reference belng had to the accompanying drawings.

The object of this invention is to provide a very simple and efiicientdevice for securing a cable to a suitable load-container adapted to belifted. More particularly the device provides means whereby the cablemay hang in a bight about'the pm or ball of a bucket, my clamp servingto gulde the cable reach above the bight and eflectlvely anchor the freeend of the cable. I

My device comprises a block formed with a guide for the main reach ofthe cable and an automatically acting wedge clamp for looking to theblock the end portion of the cable. The construction allows the cable tobe readily passed beneath the supporting member of=the bucket and thenlooked in the block, the block bearing against the upper side of thebucket pin and the bight of the cable drawing tightly about the lowerside. The weight of the bucket insures the wedge lock being drawntightly to its seat so that slipping is impossible. However when theweight is relieved the wedge may be readily driven out from the bottomto free the cable whenever desired. The invention is hereinafter morefully explained and the essential characteristics are summarized in theclaims. 7

In the drawing, Figure 1 is a side elevation of a bucket, a supportingcable and my clamping device; Fig. 2 is a sectional elevation of theclamping device on a larger scale; Fig. 3 is a cross section thereof;Fig. 4 is a perspective view of the locking wedge.

As shown in the drawings, the clamp consists of two members, namely, theblock 10 and the wedge 20. Each of these parts may conveniently be steelcasting, or other means of manufacture may be employed, if desired.

The block 10 has a cylindrical opening 11 through it near one edge,While extending from about the middle of the block to a point near theother edge is an opening 12 which converges downwardly, this openinghaving flat sides 13 and rounded edges 14. Between the two openings theblock is preferably solid, as shown at 15. Around Specification ofLetters Patent.

Y Application filed January 10, 1919. Serial No. 270,462. 7

the edge of the block is preferably made a stifl'ening bead 16.

The wedge is a member flat on its parallel 1 sides 21 and concaved onits tapered edges, as shown at 22. The upper end of the block issubstantially semi-circular and concaved, as shown at 23.-

The relative dimensions of the parts ment oned are such that when thewedge is positioned, wlth about an equal extent of it proecting belowand above, there are provided on opposite sides of the wedgeapproximately cylindrical cavities substantially equal to the crosssection of the cable. The bore of the opening 11 is sufficiently lar erthan the cross section of the cable to ena le the cable to loosely playthrough this bore.

In use the cable, designated A, in Figs. 1 and 2, passes downwardlythrough the bore 11 and .thence'loops at a, around the pin or or otherengaging portion 6 of the bucket B and thence across the top of thewedge, as shown at a and downwardly between the wedge and the other edgeof the block as at c With the device so mounted, when the pull on thecable A starts to raise the bucket the pin becomes ti htly clampedbetween the bight a and the Iower edge of the block and the downwardpull on the cable portions a a pulls the wedge downwardly tightlyclamping the cable end in place.

Experience with this cable clamp has shown that it is very effective inholding the cable to a bucket, enabling the carrying of aheavy load withperfect safety. At the same time, whenever it is desired to release thecable, it is only necessary to otherwise support the bucket and loosenthe wedge by blows of a hammer on the small end of the wedge. This atonce frees the cable.

Having thus described my invention what I claim 1s':

1. In a device of the character described, the combination of awedge-shaped block having substantially flat sides, and having acircular passageway through it adjacent to one edge, and a taperedpassageway adj acent to the other edge, the top of said taperedpassageway being wider than the bottom, and a grooved wedge adapted tobe seated in the tapered passageway and clamp a cable, the end portionof which loops around the wedge and the intermediate portion of whichdepends in a bight between the wedge and the said tubular passageway,whereby. the cable is caused to pass through edges and adapted to occupythe tapered passageway, the upper end of the wedge being rounded'andconcaved, whereby the lifting portion of a supporting cable passesdownwardly, through said cylindrical passageway and the end thereofpasses upwardly and then downwardly through said tapered passagewayforming a bight over said wedge.

In testimony whereof, Ihereunto aflix my signature.
